Speccation of Iietters Patent. A

Patented oct. 23, 19o6.

Application filed February 26, 1906. Serial No. 302,917.

To 'tbl/whom it may concern:

Be it known that I,WILL1AM'W. WAL- LACE, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented 'a new and useful Improvement iny Dumping Cars, of which the following is a specification, reference being had to the accompanying drawvlngs.

My improvement relates particularly yto dumping cars comprising' a body or box adaptedto. be tilted laterally and having a door ateach side to be opened for the lateral discharge ofthe load.' i The object of the invention is to produce mechanism for automatically shifting either ofthe doors into the open and closed positions. l

i I he improvement is' applicable tothe zodumping'- car made the subject-matter of Lettersy Patent of the United States, No 781,577, granted tome January 31, 1905. In the car described by said patent thev door atthe lower side ofthe tilted car is relatively i5l elevated and suspended at its upper corners fromtwo bars, while thelower edge of the door is free toswing' outward away from the car-body to permit the readypassage of the load of material from the carl-body, a locking- 3o ybar being appliedto each lower corner ofv said door and to the end of the car inpro er relation to'lock said door after the latter as been closed.`

y.The-object of the ,presenty improvementis.

to modify the means for liftingthe door and to'providezautom'atic means `for positively' swinging )the lowerjportion'of the door against the car-body while the door descends ithrough the lower portion of its .up and down;

4o range of'movement, sothat the entire action' ofthe door duringthe return of the car-body into' the, ,hori`zontal position is positively automatic. f y y, l y

In the accompan'ymg drawings, Figure, 1

ners of the car-body. Fig. 8 is a detail view 55 of a modification, showing arm and shoulder for turning the door. l

Referring to said drawings, 1 1 1 are upright bearing-blocksv arranged in a horizon- 'tal line extending lengthwise over the middle Ilongitudinal line of the truck. Said bearingblocks rest upon longitudinal beams 2 2 and said beams are supported upon cross-,beams 3 3. To the outer ends of said cross-beams are secured longitudinal plates, 4,'5, 5, and 6, and said plates support axle-boxes 7, which y receive the ends of the axles 8, and said axles fare vsurrounded by wheels 9, resting lon the `rails 10. Said bearing-blocksl 1 have horizontal bearings 11, arranged in the same 'horizontal line. The car-body'B is support-t' ed pivotally 'in said bearings, so thatI said vbody may tilt toward either side of the truck. Along the bottom 12 of the car-bodyi's a sill 13', parallel to the length of the car and mid- ,way between its sides. Above veach bearingl Iblock 1 a bearing-block 14 is applied to the @lower face of said sill 13. Said block 'is re- 4 cessed transversely to receive they upper portion of the `adjacent bearing-block 1, and a 8o bolt 15 extends horizontally through the f-bearings of said two bearing-blocks and is. .secured in any suitable manner, as by means :of a key or cotterv 16, extending through the free end of the bolt adjacent the bearing. iblock 14. l The body B comprises the relatively sta- ;tionary 'floor or bottom 12, the relatively sta-4 tionary end walls 17, and the shiftable walls or doors 18. As the doors'are .preferably du- `plicates, only one need be described in detail, j and as the mechanism at one end of eachv door is a duplicate of the mechanism. at the other end of the door the mechanism at only one end 'need be described in detail. Obviously thev car may have only' one door. Each door is supported'by a bar 19, hingedto `the door near the upper corner of the-latter. @To form-said hinge, the drawings show earsV 20, applied to the outer face of the door adj a- .cent to said bar and having journals .21 ex- ;tending through saidbar and Cotter-pins 22 extending through said journals outside of said bar. l The bars 19 havetheir innerends hinged to the car-body to permit movement in a plane parallel to the endwallscfthe car. For convenience and econornyiinconstruction I have shownin the drawings the endsfof ioo . hinged to one end of a link 27 by a horizontal bolt 28. rlhe opposite end of said link 27 loosely surrounds the outer end of the adj acent bolt 15, which extends through the adjacent bearing-blocks 1 and 14. F rom the foregoing description it will be seen that said lifting member 26 controls the adjacent bar 19. When the car-body is in the horizontal 1position, the lower end of each lifting menier is a little above the adjacent horizontal plate 4, and each such member is suspended from the adjacent bar 19, and the latter is supported by the hinge-bolt 23 and the adj a cent" door, the latter resting upon the carbody, as will be hereinafter described. When the car-body is moved from the horizontal into the tilted position, as shown by the dotted lines in Fig. 1 of the drawings, the lowei end of the lifting member 26 at the side of the l.car-body which is lowered soon rests upon the adjacent plate 4 and is thereby prevented from descending farther. Hence as the side of the'car descends farther the adjacent bar 19 and the adjacent door 18 are held against farther downward movement, excepting the limited downward movement due to the lowering of the upper end of said lifting member by the outward turning of said member upon its lower end in response to the lateral or outward movement of said bar 19 by the lateral movement of the hinge-bolt 23, to which the inner end of said bar is secured.

Chains C, attached to each side of the carbody and the adjacent portions of the eartruck, serve to hold the car-body in the horizontal position. When the load is to be dumped, the chains opposite the discharge side of the car are released.

To the lower corner of the door is secured another ear 20, also having a journal 21, and said journal extends through a bar 29, which is normally approximately parallel to the bar 19. The inner end of said bar is connected, as will be hereinafter described.-

A horizontal reinforcing-plate 3() extends across the middle portion of the outer face of each lend wall approximately in line with the outer ends of the bars 29. of eachbarl29 is hinged one end of a link 32 by a'ho'rizohtal bolt 33, and the opposite end of' each such-link is hinged on a horizontal stud or bolt 34,'.extending outward from the plate ,30 ata point between anda little above To the inner end the two hinges of the adjacent bar 29. To impart to said stud or bolt 34 greater Istability, a bracket-plate 35 is applied by its outer edge to the reinforcing-plate 30 and extended thence outward and upward and around the outer end of said stud. To clear said stud, the inner half of said bar 29 is curved upward, as shown in Fig. 1. The space between the reinforcingeplate 30 and the bracket-plate 35 is sufficient to allow the bar 29 and the link 32 to rest side by side between said plates.

ln the closed position, (indicated by solid lines in Fig. 1,) as already described, the outer hinge of the link 32 is above the two hinges of the bar 29. Hence any outward pressure exerted against the lower portion of the door is resisted by said link 32, for the strain imparted to said link through the bar 29 will be on a line below the stud 34, and there will be no tendency to lift the outer end of said link. On the contrary, the tendency is to draw the outer end of said link downward. Thus the lower portion ofthe door is very securely locked, so long as the car-body is in the horizontal position and the inner end of the bar 29 is not lifted by hand; but when that side of the car-body is lowered, as already described, the adjacent lifting member 26 relatively lifts the adjacent bar 19, whereby the adjacent door is lifted, and the outer end of the adjacent bar 29 is lifted until the line cutting the hinges of said bar is above the outer hinge of the lilik 32, or it might be said that said side of the car-body descends more rapidly than the adjacent bar 29, whereby the stud 34, to which the outer end of the adjacent link 32 is hinged, is carried downward below the line cutting the hinges of the bar 29. Thus the inner end of said link may rise and permit the bar 29 to move bodily outward. Such outward movement may continue until the inner hinge of the bar 29 is between the outer hinge o said bar and the stud 34 and in line with said outer hinge and said stud; but in order to facilitate the closing of the door when the car-body is again brought into the horizontal position it is preferable to limit the downward movement of the inner end of said bar 29, so that the hinge which joins said bar and said link will remain a little` above a line cutting the outer hinge of the bar 29 and the stud 34, whereby said link is free to turn upward and inward on said stud. To thus limit the downward movement of the bar 29, any suitable stop may be applied to the car in such position as to engage said bar or said link when said bar has descended to the desired limit. For this purpose the drawings show a stop-block 36, applied to' the outer face of the end wall of the car in proper position to meet they swinging end of the link 32 when the bar 29 has descended as far asdesired.
